Halak, 27, has appeared in five games this season posting a 3-0-0 record including a 2.10 goals-against average and an .889 save percentage, and is tied for the NHL lead with two shutouts. He had been out with a groin injury.
The Blues are 0-3-1 since starting the season with six wins in their first seven games.
The team also assigned goaltender Jake Allen to their American Hockey League (AHL) affiliate, Peoria Rivermen.
We have no doubt how he can play. You don't, with four teams that are left, you're not getting here without good goaltending. All great goalies left, and [Bishop] is a top-tier goaltender in this league and he's shown it.
